Selecting SMDR Transmit Rate
The DX-120 system allows you to specify the transmission rate of SMDR data consisting of:
• eight (8) bits
• one (1) stop bit
• no (0) parity
• The system outputs SMDR from the standard “SMDR” RS232 serial port located on the Central Processor Module
(CPM). You can connect an external serial printer or call accounting device for permanent record keeping or call
cost accounting.
• The system outputs each data record within the standard 80-character frame. Data communications occur in one
direction only through the SMDR port; you can program the baud rate during system programming.
• SMDR information includes the following:
- call direction, or a comment for special call handling record
- extension number
- CO line used
- number dialed
- ring time to answer
- time and date the call was placed
- duration of the call
- account code (if specified)
• The system also provides ring-in duration and call processing information relative to the call as it was handled by
the system.
• The system outputs two records for incoming calls that are received with Caller ID (although this feature is a
standard feature of the DX-120, a telephone company subscription is required).
- The first record lists the telephone number of the calling party as it is received from the telephone company
(calls from CID blocked numbers will not have a CID number associated with that record).
- The second record will show the caller’s name (“OUT OF AREA” or “PRIVATE” may appear in this field if the
calling party number is unavailable.)
EXAMPLE
The following is an example of an SMDR report. In this example, the two “I” records
are one incoming call record received with caller ID.
